expected <string> but got <EOF>

[Haffon]

This is the json file demo-blank-line.json content:

{
    "node_name" : "test_node",

    "log_valid_days" : 7
}

This is the jawk command line:
./jawk '{print _["log_valid_days"]}' demo-blank-line.json
and this is the command output:

demo-blank-line.json: expected <string> but got <EOF> (length 3) at input token 1
<<EOF>>

if I remove the blank line of demo-blank-line.json to make it look like this:

{
    "node_name" : "test_node",
    "log_valid_days" : 7
}

and run the same command line again, then it output:
7
My questions is:

1. Why command failed just because of one blank line difference?
2. Why need patch JSON.awk with patch-json-awk.diff?
3. How can I use jawk with blank line json file?

Thank you for this report! This is fixed in fc4f17c. To answer your questions:

1. This was because of a bug in a modification I made to JSON.awk.
2. To handle line-delimited JSON, and it's also needed for some other features in jawk.
3. It should work now!

@mohd-akram Thanks, it work for simple json file now, but I have a little long json file, which cause the jawk command output:

some-long.json: expected <string> but got <EOF> (length 3) at input token 5
"type_id" : 1 , <<EOF>>

[mohd-akram]

Hmm, odd. Does this happen with JSON.awk too or just with jawk? Could you provide the file? If not, do you think you'd be able to reduce it to a small sample where the error happens?

[Haffon]

@mohd-akram It does not happen with JSON.awk 1.4.2. I'm trying to reduce it to a small sample, see you soon.

[Haffon]

The full file has another special character, which display as ^I when set option with :set list in vim, and it make a little hard for me to copy and paste the text. even to reduce it to a small sample.

[mohd-akram]

Hmm, okay. Could you paste the full error message that you get? I might be able to figure it out that way.

EDIT: It seems you did paste the full error but it got parsed in a strange way due to markdown. It's better to wrap errors/code in triple backticks, like so:

some-long.json: expected <string> but got <EOF> (length 3) at input token 5
"type_id" : 1 , <<EOF>>

Okay, I can reproduce the error now.

[mohd-akram]

This should be fixed in b5167c4.

Thanks for you fixing.
